Thank you all. As I said, it's not really about the money or the currency exchange rate. It's really about the experience. It's very rare my future husband and I can both take 10 days and more off together for a holiday. We want to go somewhere special. So that's why I can't decide. But as SUPERHAPPYLUN said, Japan is relatively close to HK and I can take short trips there whereas Australia requires more time and distance. I am leaning towards Australia at the moment.
